Creating An Effective Visual Analytic Environment

We are developing visual analytic environments for the communication of
information and insight from massive, disparate, incomplete, and
time-evolving homeland security data sets. Our environments are
comprehensive, providing analytic capabilities that enable the entire
process from receiving massive raw data, to the integration and extraction
of relevant data necessary for the information analysis task, to the
integrated visual presentation and analysis environment for evidence-based
planning, decision making, and response.

In developing this environment, PURVAC focuses on three important and
representative homeland security challenges that can benefit from
systematic analysis of massive data: emergency planning and response,
mobile analytics, and healthcare management and monitoring. All three of
these challenges require improved strategies for exploratory visual
analysis of data as well as the user-specific presentation of relevant
information as a basis for actionable decision making. PURVAC integrates
and builds upon our team's proven expertise in novel visualization
techniques, perception, statistical modeling, data management, privacy,
health-care management, event simulation, and evaluation to develop new
task, user and display specific integrated visual representations for
these applications.
